XCELL quality CO2 cartridges can be used in Mountain or Road racing to save energy and time when pumping up flat tyres. A must have for any performance orientated cyclists.

Continental GP 4000 S II - are the latest evolution in a tyre that can only be described as legendary in the world of bicycle racing - probably more kilometres have been done and are being done day in day out around the globe than any other tyre on Earth. Continental GP 4000 tyres are known as the perfect all-rounder for all conceivable conditions

In the research and development laboratories for Continental bicycle tyres in Korbach, Germany, the staff and engineers have been looking for the solution to one of the fundamental problems of tyre construction:

The running properties of the rubber compound of a tyre are largely determined by three interacting factors:

1. static friction (grip)

2. rolling resistance

3. mileage

The dilemma is that you improve one of these factors, and in turn, worsen at least one other factor. A tyre with maximum grip wears out faster and rolls slower. If one makes the tyre faster or more durable, then this in turn reduces grip.

With the then current highest standard of compound technology, the Activated Silica Compound having already reached a very high standard of compromise, our developers wanted to take compounding to an even higher level. This lead them to venture into new territory, exploring new ways so that in 2005 they made a breakthrough in mixing technology, the first steps to what is now known as BlackChili.

This revolutionary compound is based on the latest findings on polymer and other raw material research.

For BlackChili we refine newly developed synthetic rubbers with natural rubber with the proven high-performance tread compound.

We use these rubbers with special nanometric carbon soot particles, which are optimized in shape and surface properties for best uses for the intended tyre.

BlackChili technology never stands still as it is continuously developed and tailored to the individual applications of new Continental tyres as they continue to be produced out of the German Korbach factory.

Whether on the road or mountain bike, speed and grip advantages are very noticeable.

The complex compound technology is so sensitive that tyres with BlackChili Compound can only be produced exclusively in our German Korbach factory.
